Many of us have had that moment where something about a food or drink order at a restaurant doesn’t feel quite right when it comes, especially if you’ve had any kind of negative encounter with the wait staff. But in one case, police say they were able to prove which waiter at a Chili’s restaurant had spit into a customer’s takeaway drink, using DNA analysis.

A representative for a Sonic restaurant in Eunice, Louisiana has admitted that two of their employees were spitting in customers’ drinks. “It was brought to my attention by the manager of the store that the incident was brought to his attention that an employee had spit in a drink of a customer,” said the rep. Oh, good. So long as something was brought to someone’s attention.
